The vehicle was brought to an authorized GM dealership for a scheduled appointment to address a check engine condition related to a purge valve and an open safety recall for the lower control arm. The VIN was provided and confirmed at the time the appointment was made; however, the recall was not completed during the visit. The dealership replaced the purge valve without documenting diagnostic testing to confirm the cause or verify the repair. The vehicle was returned with the same check engine light still present. Additional issues were communicated through technician video and text, including a potential oil leak and possible fluid mixing, but none were documented or diagnosed in the service record. A dealership manager later stated that the vehicle was “not safe to drive,” but no written explanation or safety guidance was provided, and the vehicle was released without clarification. No diagnostic records, technician notes, or findings have been provided by either the dealership or GM despite escalation. The consumer has worked through appropriate dealership and manufacturer channels for approximately one month without resolution. The consumer is now being directed to return the vehicle for additional diagnostics at the consumer’s expense without defined scope or explanation. The vehicle remains with an unresolved condition and an open safety recall, without clear guidance regarding safe operation. This lack of clear, documented information is particularly concerning for senior-aged owners who rely on accurate guidance to make safe decisions.

I purchased my vehicle on January 6, 2025. Two days later, the check engine light came on. After struggling to reach anyone at the dealership, I finally got in touch on January 14, and dropped the car off on January 22 for a catalytic converter and A/C issue. On February 23, the check engine light returned with the same code. I brought the car back on March 7, and by May, the light came on again and the A/C failed for a second time. Over 1–2 weeks, I called repeatedly but was either hung up on or transferred with no resolution. On May 23, I had the car checked at an independent shop, who confirmed it was the catalytic converter again and recommended I return to the dealer. I made an appointment online and dropped the car off on May 29. I didn’t hear anything for nearly a week. When I called, the same communication issues happened. On June 3, my sister picked up the car — it was a mess, with the back seat torn apart. I was told it wasn’t the cat but a fuel pump, water pump, and quoted over $2,000. I got a second opinion on June 22. That mechanic said it did not need a fuel pump and that it was the cat — plus spark plugs, coil pack, serpentine belt — none of which had ever been mentioned before. I’ve since spent $600 on repairs that shouldn't be necessary months after purchase. Emails to the service team went unanswered until I followed up. The car also had an ongoing rotten egg smell.On June 30, I was told they’d replace the aftermarket cat with an OEM. I emailed asking about the A/C and a service history — no reply. I dropped the car off July 2 or 3, was told it’d be ready July 7, then July 8, then told the issue was actually a cracked turbocharger, not the catalytic converter. I asked if it was safe to drive — the manager said yes, but everything online said otherwise. I was told the part would arrive in 1 day and take 2 days to replace.As of July 15, the car is still not ready. Trenton told me in person the part still hasn’t even arrived and would take 5 more days

2016 Chevrolet Trax experienced turbocharger failure in June 2024. Initial minor acceleration inconsistencies progressed to dangerous turbulence and power loss during acceleration at both high and low speeds, with check engine light temporarily illuminating. Initial Firestone diagnostic (June 7) documented 'TURBULENCE AS ACCELERATES - CEL BLINKED.' After diagnosis, completed repair June 11. Searched for recalls at time of failure but found none listed. Given 50-minute highway commute and unsafe acceleration issues, immediate repair was necessary. Due to expected dealer costs and wait times, repair was completed at Firestone Complete Auto Care for $3,036.81. Double-checked for recalls after repair with no results. On February 3, 2025, while organizing digital records, discovered original GM Special Coverage Program notice from November 2021 covering turbocharger wastegate actuator linkage issues. Program promises coverage for 10 years/120,000 miles. At 68,283 miles, vehicle is well within coverage period. On February 3, 2025 at 4:19pm, called GM customer service (case #[XXX], 29 minute call). Rep Takesha spoke with supervisor Britney but refused transfer. Put on hold 4 times totaling over 6 minutes. When requesting Special Coverage Program information, rep repeatedly stated 'it was not done at a dealership' over 15 times as blanket response. Initially cited expired bumper-to-bumper warranty from 2019 (irrelevant to Special Coverage). When pressed, shifted to claiming 'no active recalls' for VIN. Stated 'the decision has already been made, and a supervisor will tell you the same decision,' refusing escalation or document review. All attempts to discuss Program terms met with same non-dealer repair response. Refused to provide submission process information or contacts.
